Lagging/late frames -- PC falling behind.
Dropped frames -- Connection falling behind.

You are indeed experiencing dropped frames; which is no surprise. Given you're streaming at 4000 Kbps. I am going to assume you simply cannot maintain that bitrate. Nor should you try to, given the fact Twitch prefers people not going over 3500 Kbps.

Regardless, I would suggest running an upload test here, making sure to test to a server near the one you've been streaming to. To get a really accurate estimate of what you can maintain to that server.

No, I did not link you to SpeedTest. Please run the test I linked; SpeedTest is not suitable for streaming purposes, its method of testing is completely different from the strain a stream puts on your connection.

You saw the result yourself. A result tested to a site that does not belong to OBS, does not belong to Twitch. So, no overhaul or anything has affected that result.

And I am going to assume you were streaming at VBR 4000 Kbps. And simply never reaching that 4000 Kbps. So, tone the bitrate down substantially. Try CBR 2250 for now. 720@60 FPS should still look quite good at 2250 Kbps CBR. To improve on the quality you can easily drop the CPU Preset down a couple of notches. Your CPU should have no issue running it at Fast instead of Veryfast.
